SPECIFICATION forming part of Letters Patent No. 445,471, dated January 27, 1891.

Application filed June 23, 1890' Serial No. 356,442. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDGAR A. HOLLISTER, a citizen of the United States, residing at VVelch Glade, in the county of Webster and State of Vest Virginia, have invented certain new and useful Improvements in Flows; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in.

hillside-plows; and it consistsin certain novel features of construction hereinafter described and claimed.

In the accompanying drawings, made a part of this specification, Figu e l is a perspective view showing the beam in position for turning.- Fig. 2 is a side elevation. Fig. 3 is a top plan view. Fig. 4 is a longitudinal vertical section on line 03 41:, Fig. 3.

The object of my invention is to provide a plow that is especially adapted for plowing steep hillsides, as it is constructed with two moldboards, points, and shares, and is therefore practically two complete plows so formed and connected that their relation to each other is reciprocal.

In the following detailed description I will refer to the several parts by letter, of which A is the beam, constructed and provided with handles a Ct in the usual manner, except that the former is heavier or stronger at its middle, at which point a vertical cylindrical hole B is made in the beam, through which passes the post 0 of the plow. This hole is properly re-enforced or lined with sheet metal, so as to prevent undue wear by contacting with the post. In front of and behind the hole B are the rectangular holes or mortises D, which extend upward nearly through thebeam and provide seats for the colters E.

The cutting parts of the plow proper are duplicated, one set being placed immediately behind the other, the noses or shares pointing in opposite directions; but the mold-boards are on the same side. The landside is one continuous piece, reaching from nose to nose. The post or standard 0 extends above the beam, and is provided with the swiveled head F, to which is attached an operating-lever G, the front end of which is pivotally secured to the beam by the bifurcated end of the support II, while the free end of such lever extends backward to a point convenient for the operator.

The post 0 is adapted to move longitudinally and pivotally inthe hole B, and by being forced downward by the lever G disengages the colters from the holes or mortises D. and thereby enables the cutting parts of the plow to be reversed. The upper ends of the colters are provided with grooves near thei top and upon each side, by which they are secured in position in the mortises by a forward movement of the lever I, which is properly secured to the beam by staples J. The lever is provided with two inwardly-projecting teeth K, which are adapted to engage with the grooves in the top of the colters, as will be readily understood. Grooves are placed upon each side of the end of the colters, so that the same may be secured in position when reversed. The rear end of the lelever I upon its upper side is provided with a notch to receive the dog L, and this notch is so placed that the teeth K will be locked into engagement with the colters. In like manner 1 provide the dog M, which is secured to the rear end of the beam and reaches sufficiently upward to engage the lever G, when such lever is brought downward so as to force the colters out of the inortises.

In operation it will be seen that the plow is so constructed that it can be used in the usual manner, and that when the end of the furrow is reached and it is desired to turn the plow the rear end of the lever G is forced downward, thereby forcing the colters out of the mortises, when the beam may be rotated upon the post, so that the colters will change position when the lever G is raised, permitting such colters to enter the mortises, where they may be secured by a forward movement of the lever I, which in turn is secured by the dog L.

While my plow is especially adapted to plow steep hillsides, it is also equally useful as an ordinary plow. I

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. A reversible plow having the centerpostadapted to pass through the beam, the col ters extending from the noses and reaching I oo upward into the mortises provided on the under side of the beam, the lever I, adapted to secure such colters in the mortises by means of the inwardly-projecting teeth tl1ereon,-the swiveled head upon the post, and the operating-lever secured thereto, adapted to force said post downward, enabling the beam to rotate thereon, substantially as described.

2. In a reversible plow, the combination of the shares, the upwardly-extendin g eolters secured thereto, the center post journaled in the beam and extending above the same, while it is engaged by the swiveled head attached to the operating-lever, the locking-lever I, having the inwardly extending teeth, the operating-lever G, pivotally secured to the beam by means of the bifurcated standard, as shown, the swiveled head upon the post, and the locking-dogs L and M, adapted to secure the lever, substantially as described.

3. A reversible plow having the cutting parts thereof duplicated, as shown, the center post extending upwardly through the beam, which is adapted'to rotate thereon, the duplicated colters extending upward from the noses of the shares and arranged to be secured in the mortises 011 the under side of the beam, the locking-lever I, having the inwardly-projecting teeth K, arranged to secure the colters by entering the grooves provided therein, and the operating-lever G, pivotally secured to the beam and the swiveled head of the post, substantially as described, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
